5 Claims.

This invention relates to a marginal gluing machine.

An object of this invention is to provide a gluing machine whereby a ribbon of glue f predetermined width may be applied to a sheet.

Another object of this invention is to provide an improved means whereby a ribbon of glue may be applied to a sheet which may be polygonal, round or of other irregular or regular shape.

A further object of this invention is to provide a machine of this kind, including an improved wiping means for the gluing roll so that a pre determined quantity or depth of glue will be transferred from the gluing roll to the sheet.

A further object of this invention is to provide in, a machine of this kind, a removable mounting for the operating mechanism so that the operating mechanism may be bodily lifted from the glue well or base for cleaning or other purposes. A further object of this invention is to provide in a machine of this kind, an improved adjustable means whereby the width of the applied glue ribbon may be regulated.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawing and specifications, and then more particularly pointed out in the appended claims.

Figure 9 is a fra mentary sectional view taken on the line 9-9 of Figure 8,

Figure 10 is a top plan view of the fixed base and the removable securing means for securing the removable operating mechanism on the fixed base,

"Figure 11 is a bottom plan View of the base carried by the removable operating mechanism.

Referring to the drawings, and first to Figures 1 to 6 inclusive, the numeral I5 designates generally a base structure which is formed of upright side walls It and upright end walls I1 and.

l8. bottom wall I9 is secured between the op...-

posite side walls It and the end walls ll and; I8

at a point above the side and end walls and forms a well or reservoir 2!] within which glue is adapted;

to be positioned.

The bottom wall I9 is formed with a pair of downwardly projecting lugs or ribs 2| on the lower side thereof, on which a heating element 22 is adapted to be secured. An insulating plate 23 is secured to the lugs 24 by fastening means 25 and is spaced downwardly from the heating element 22. The base structure l5 includes an upwardly projecting standard 26 adjacent one of the side walls which forms a guide for rollers and feeding means as will be hereinafter de scribed.

A gluing roller 21 is secured to a shaft 28 which is journaled through the standard 25, and the shaft 28 hassecured thereto a spur gear 29. The

spur gear 29 meshes with an intermediate gear; 30 rotatably carried by the standard 26, and the gear 39 meshes with an upper ear 3| also rotatably carried by the standard 26. The gear 30 has fixed relative thereto a, large speed reducing gear 32 which has meshing therewith a small spurgear 33, and the gear 33 has fixed relative thereto a large grooved pulley 34.

A motor 35 is disposed at one end of the base structure, as shown in Figure 1, and the shaft 36 The guide 39 includes a vertical side 42 which is cut out as indicated at 43, the purpose for which will be hereinafter de scribed.

The guide or table 39 is secured to a block 44.

which is carried by a rod 45, being fixed relative to the rod 45, and the rod 45 is secured tofa" block 46. The block 45 is secured to an elongatedff rod 41 extending through the standard 26,a'nd;

lengthwise adjusted with respect to the standard 26 sF'that the table 39 may, if desired, be e'ndwisef adjustable.

A pair of rollers 48 are disposed above the roller 21, being disposed with the axes thereof parallel to each other and with the roller 21. The rollers 48 are each formed with a peripheral" groove 49 within which the vertical side 42'of the table 39 is adapted to loosely engage. Each roller 48 is fixed to a shaft 50 which is journaled v through a bearing 5| and the two bearings 5! are connected together by connecting webs 52 The bearings 5| are adapted to be vertically adjusted, by means of an adjusting screw '53 so that the ferred from the gluing roller 21 to the sheet 7 the slot 51' so that the plate 56 will scrape substantially all of the glue from the sides of the roller 21. The upper or outer end 58 of the slot 51 is adapted to be adjusted toward or away from the peripheral surface of the roller 21 so that the desired amount of glue will be retained on the peripheral or gluing surface of the roller 23.

The plate 56 is secured by fastening means 59 to an elongated supporting bar 6! and the bar 60 is secured to a block 51. The block 61 is slidable on the bar 47, being held against rotation by means of a key 52. The block 6i extends above the bar 51 and has loosely disposed therethrough a bolt 63 which is fixedly secured as at 64 in the standard 26. An adjusting nut 65 is threaded on the bolt 63, bearing at one end against the block 6 I, and a spring 66 is interposed between the block SI and the adjacent side of the standard 26. The spring 66 constantly urges the block 6| outwardly.

The motor 35 is connected to a switch 61 and this switch may also be connected to the heater 22. A rheostat 63 is connected with the heater 22 so that this heater may be energized to the desired degree.

The reservoir 20 is adapted to be emptied by means of a valve 69 mounted on a pivot member Ill, engaging against end wall l1, and a handle H is carried by the Valve 59. A stop bolt 72 is adapted to lock the valve member 69 in closed position. The gears and the pulleys associated with the operating mechanism are adapted to be enclosed in a'cover or shield 13 which is secured to the upper end of the standard 26, the shield 13 having a strap 14 extending from the upper side thereof which is engageable with a fastening member carried by the upper end of the standard 26.

Thegluing well is covered by means of a stepped cover plate 15, and the plate keyway I8. A standard 26a, similar to the standard 26, engages on the block 21, the standard 26a being formed at its lower end with a base plate 19 having a transversely extending key 80 which is engageable in the keyway 18. The block I! has secured thereto a pair of eye bolts 8|, including a threaded shank 82. The bolts 8! are pivotally mounted on pins 83 which extend transversely through the base block H, and the base member 19 is formed at the opposite ends thereof with slots 84.

j Nuts 85 threaded on the shanks 82 are adapted to removably secure the standard 26a on the base block 11. In the present instance a relatively wide gluing roll 86 is rotatably carried by the glued will engage between the feeding rollers 4 standard 26a and the gluing roll 86 has associated therewith a pair of feeding rollers 81. The operating mechanism for the rollers 86, 81 is identical with the operating mechanism for the roller 2'! and the rollers 48.

The fixed or base block I1 is secured by fastening means 88 to a pair of upstanding ribs or flanges 89 which are carried by the bottom wall I9a. It will be understoodthat the gluing roller has associated therewith a glue regulating member 55a which is similar to the regulating member 55 and is adjustably mounted in the same manner as the regulating member 55.

In the use and operation of this device, the sheet of material which may be cardboard 91' other fibrous material having a degree-of flexibility and a degree of rigidity, is adapted: to'beengaged with the horizontal side Ml of the table 39. The marginal edge of the sheet which is being glued is engaged between the feeding rollers" 48 and the feeding rollers 48 are then vertically adjusted by the adjusting screw 53. The wiper 55 is adjusted relative to the roller 21 so as to provide for transfer of the desiredthickness of a gluing ribbon on the sheet. This sheet which is being glued may be of any desired configuration, that is may be either rectangular, round, cval, or of irregular configuration. Y

The structure shown in Figures 7 to 11' inclusive will operate in the same manner as the structure shown in Figures 1 to 6, with the exception; that the table 39a may be adjusted relative to I the gluing roller '21 so that the desired width of the marginal edge of the sheet which is being 81 and the gluing roller 85.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.
